Builder Assistant

Builder Assistant is a lightweight Minecraft Fabric utility mod for faster building, testing, and world editing through simple in-game commands.

It allows players to quickly clear, fill, and undo block areas around their current position. Areas can be selected either from the player's center position or forward in the direction the player is looking.

Features

Clear blocks in a custom-sized area
Fill areas with a selected block
Use centered area selection around the player
Use forward-facing area selection based on the player's view direction
Undo the last clear or fill operation
Simple command-based workflow
Useful for builders, map makers, testers, and modpack development

Commands

Clear Area

/h_ba_clear_area <distance> <width> <height> center

Clears blocks around the player, using the player as the center of the selected area.

Example:

/h_ba_clear_area 10 10 10 center

This clears a 10 × 10 × 10 area around the player.

/h_ba_clear_area <distance> <width> <height> current

Clears blocks starting from the player's current position and extending forward in the direction the player is looking.

Example:

/h_ba_clear_area 10 2 2 current

This creates a forward-facing cut that is 10 blocks long, 2 blocks wide, and 2 blocks high.

Fill Area

/h_ba_fill_area <distance> <width> <height> center <block>

Fills a centered area around the player with the selected block.

Example:

/h_ba_fill_area 10 10 3 center minecraft:dirt

This fills a 10 × 10 × 3 area around the player with dirt.

/h_ba_fill_area <distance> <width> <height> current <block>

Fills an area in front of the player with the selected block.

Example:

/h_ba_fill_area 10 2 2 current minecraft:oak_planks

This creates a forward-facing 10 × 2 × 2 block area made of oak planks.

Undo

/h_ba_undo

Restores the previous clear or fill operation.

Example:

/h_ba_undo

Area Modes

Center Mode

The center mode uses the player's position as the center point of the operation.

This is useful for clearing or filling rooms, platforms, testing zones, construction spaces, or areas around the player.

Example:

/h_ba_clear_area 15 15 5 center

Current Mode

The current mode starts from the player's current position and applies the operation forward based on the direction the player is facing.

This is useful for creating tunnels, corridors, straight cuts, bridges, walls, and forward-facing block placements.

Example:

/h_ba_clear_area 20 3 3 current

More Examples

Clear a small room around the player:

/h_ba_clear_area 10 10 5 center

Clear a tunnel in front of the player:

/h_ba_clear_area 20 3 3 current

Create a dirt platform around the player:

/h_ba_fill_area 15 15 1 center minecraft:dirt

Create a stone wall in front of the player:

/h_ba_fill_area 10 1 5 current minecraft:stone

Create a wooden bridge in front of the player:

/h_ba_fill_area 20 3 1 current minecraft:oak_planks

Undo the last operation:

/h_ba_undo

Notes

Builder Assistant is intended to be a simple and practical building helper, not a full replacement for advanced world-editing tools.

The mod focuses on fast, readable commands for common building and testing actions.

The undo command currently restores the last clear or fill operation performed by the player.
